In his masterful book, Trefil shares with readers some of the most recent research in neurology, evolution, primate research, computer science, and philosophy. Trefil's prose is lively and engaging. --Boston Globe

Trefil's race through the science that could explain the brain is highly readable. --Sunday Times of London

In a provocative essay, Trefil argues that the science of artificial intelligence is progressing rapidly. Machines, he theorizes, will one day develop a new kind of intelligence and self-awareness. So, maybe the real question is: Are we ready? --San Diego Union-Tribune

A highly readable and engaging treatment of a fascinating question. Trefil makes a case for human uniqueness while at the same time celebrating the achievements of creations ranging from lobsters to neural nets. A provocative and enjoyable book. --Daniel L. Schacter Professor and Chair of Psychology, Harvard University author of Searching for Memory
